EMP Survival: 3 Ways To Build A Faraday Cage

from Survivopedia:

Storing a few key electronics that would be of use in a protracted power grid failure will ensure that you’ll still receive information, communicate and carry out other critical functions in the event of an HEMP. It’s common knowledge that a Faraday cage is the safest way to protect them.

Faraday cages shield their contents from electromagnetic energy. If you have ever had a magnetic resonance imaging or you have been inside one, though you may not have even noticed.

How hard is it to build this device by yourself? Read this article to see three simple Faraday cage designs you can build at home!

A HEMP is a multi-pulse of strong electromagnetic fields generated when a nuclear weapon is detonated high in the atmosphere which could cripple the power grid of a city, or even the entire lower 48 states if more than one weapon is used, or a weapon is detonated at sufficient altitude.

Faraday cages are not necessary to protect most electronics from the type of an Electromagnetic Pulse (EMP) caused by solar storms (magnetohydrodynamic EMP.) To protect most electronics from that EMP, you just need to make sure that your equipment is not connected to the grid and then have a renewable energy source to power it without the electrical grid.

I hosted a series of EMP Q&A sessions at PrepperCon 2016 for Survivopedia and a lot of people asked questions this subject there too. Given the importance of EMP preparedness, I would like to get as many questions answered as possible.

Faraday Cage Construction

One common thread throughout many readers’ questions is that there is conflicting information online about Faraday cages. While building a Faraday cage does not have to be a complicated endeavor (if you keep it small and simple with no penetrations in the shielded envelope), there are some gaps in the public sector knowledge on the subject and quite a bit of conflicting information online.

Faraday cages are EM (electromagnetic) shielding and must be properly designed and implemented or they can cause more harm than good by acting like an EMP antenna instead of an EMP shield.

How to Build a Faraday Cage

Building a Faraday cage can be very simple. Here are a couple of designs to build by yourself:

1. Aluminum Pressure Cooker Faraday Cage

Line an aluminum pressure cooker with a large heavy duty freezer bag. You’re done! Equipment goes in the bag. Secure the lid and you are good to go.

This cage is compact and an aluminum pressure cooker provides more shielding than any other object you are likely to have in your home that I can think of.

I like this cage because it is very simple and provides so much shielding that it should protect the contents against even a super EMP weapon even if sky zero was close by. Second hand stores such as Good Will, Salvation Army or Deseret Industries are great places to find an aluminum pressure cooker cheap.

Pressure cookers are also very useful multipurpose survival items long after a nuclear HEMP or should you experience some other catastrophe as opposed to HEMP:

Pressure canning: Pressure can food to store until the next growing season or future years.
Sterilization: Sterilize bandages, sutures and instruments for medical procedures.
Cooking: Loosen the lid and use a pressure cooker as a stock pot to create stews. Stews preserve more nutrients and caloric content than grilling foods and having fats and oils that are difficult to replace under survival conditions drip into your cooking fire.
Distillation of water: You can make a number still designs with a pressure cooker and some designs using pressure cookers are more efficient than with a simple stock pot if you store a little copper tubing and a collection vessel will be cooled.
